Abstract

A battery charger circuit having a regulator controller configured to control the switching transistors of a switching voltage regulator. A power path switch is disposed intermediate an output of the switching voltage regulator and a terminal of a battery to be charged, with the power path switch including at least two transistor segments having common respective drain electrodes, common respective source electrodes and separate respective gate electrodes. A power path switch controller operates to sequentially turn ON the at least two transistor segments of the power path switch, preferably in the order of a decreasing ON resistance.
